Description
Die vorliegende Erfindung betrifft einen Laststufenschalter zur unterbrechungslosen Umschaltung zwischen verschiedenen Wicklungsanzapfungen eines Stufentransformators gemäß dem Oberbegriff des ersten Patentanspruches.The present invention relates to an on-load tap changer for uninterrupted switching between different winding taps of a tapped transformer according to the preamble of the first claim.
Laststufenschalter sind seit vielen Jahren zur unterbrechungslosen Umschaltung zwischen verschiedenen Wicklungsanzapfungen von Stufentransformatoren in großen Zahlen weltweit im Einsatz. Sogenannte Reaktorschalter, die besonders in Nord-Amerika verbreitet sind, besitzen eine Umschaltreaktanz, die eine langsame, kontinuierliche Umschaltung ermöglicht. Laststufenschalter nach dem Widerstandsschnellschalt-Prinzip bestehen üblicherweise aus einem Wähler zur leistungslosen Anwahl der jeweiligen Wicklungsanzapfung des Stufentransformators, auf die umgeschaltet werden soll, und einem Lastumschalter zur eigentlichen Umschaltung von der bisherigen auf die neue, vorgewählte Wicklungsanzapfung. Der Lastumschalter weist dazu üblicherweise Schaltkontakte und Widerstandskontakte auf. Die Schaltkontakte dienen dabei zur direkten Verbindung der jeweiligen Wicklungsanzapfung mit der Lastableitung, die Widerstandskontakte zur kurzzeitigen Beschaltung, d. h. Überbrückung mittels eines oder mehrerer Überschaltwiderstände. Die Entwicklungen der letzten Jahre führten jedoch weg von Lastumschaltern mit mechanischen Schaltkontakten im Isolieröl. Stattdessen werden vermehrt Vakuumschaltzellen als Schaltelemente eingesetzt.On-load tap-changers have been in worldwide use for many years for uninterrupted switching between different winding taps of tapped transformers in large numbers. So-called reactor switches, which are particularly common in North America, have a switching reactance, which allows a slow, continuous switching. On-load tap changers according to the resistance fast-switching principle usually consist of a selector for powerless selection of the respective winding tap of the tapped transformer to be switched to, and a diverter switch for the actual switching from the previous to the new, preselected winding tapping. The diverter switch usually has switching contacts and resistance contacts. The switch contacts are used for direct connection of the respective winding tap with the load dissipation, the resistor contacts for short-term wiring, d. H. Bridging by means of one or more switching resistors. The developments of recent years, however, led away from load switches with mechanical switching contacts in insulating oil. Instead, more and more vacuum switching cells are used as switching elements.
Bei einer besonderen Gattung von Laststufenschaltern, den so genannten Lastwählern, sind die beschriebenen Mittel zur Anwahl einer neuen Wicklungsanzapfung und die Mittel zur eigentlichen Lastumschaltung baulich vereinigt und werden gemeinsam betätigt. Üblicherweise sind Stufenschalter nach dem Prinzip der Widerstandsschnellschaltung zur unterbrechungslosen Umschaltung von einer Anzapfung eines Stufentransformators zu einer anderen so aufgebaut, dass die jeweils mit den Ausleitungen der Stufenwicklungen elektrisch in Verbindung stehenden festen Stufenkontakte in einer oder mehreren horizontalen Ebene bzw. Ebenen kreisförmig an einem Isolierstoffgerüst oder -zylinder angeordnet sind und durch von konzentrischen Antriebswellen betätigte drehbare Kontaktbrücken beschaltbar sind. Bei Lastwählern, bei denen die Stufenwahl und die eigentliche Lastumschaltung kombiniert sind, erfolgt die Betätigung der Kontaktbrücken dabei sprungartig nach Auslösung eines von der Antriebswelle des Schalters aufgezogenen Energiespeichers, meist Federkraftspeichers.In a special type of on-load tap-changers, the so-called load selectors, the described means for selecting a new winding tapping and the means for actual load switching are structurally combined and operated together. Usually, tap changer are constructed according to the principle of resistance fast circuit for uninterrupted switching from a tap of a tapped transformer to another so that each with the outputs of the stepped windings electrically connected fixed step contacts in one or more horizontal plane or planes are arranged in a circle on an insulating material stand or cylinder and can be connected by actuated by concentric drive shafts rotatable contact bridges. In load selectors, in which the step selection and the actual load switching are combined, the actuation of the contact bridges takes place abruptly after triggering a wound up by the drive shaft of the switch energy storage, usually spring energy storage.
Unabhängig vom konstruktiven Aufbau des Laststufenschalters, also mit rotierendem oder linear bewegbarem Kontaktsystem, bedarf es bei aus dem Stand der Technik bekannten Laststufenschaltern eines Federenergiespeichers zum sprungartigen Umschalten mittels des Kontaktsystems. Aus dem Stand der Technik bekannte Kraftspeicher werden zu Beginn jeder Betätigung des Laststufenschalters von einer Antriebswelle aufgezogen, d. h. gespannt. Die bekannten Kraftspeicher bestehen im Wesentlichen aus einem Aufzugsschlitten und einem Sprungschlitten, zwischen denen Kraftspeicherfedern als Energiespeicher angeordnet sind.
Es wird eine anfängliche langsame Drehbewegung der Antriebswelle genutzt, um einen Aufzugsschlitten translatorisch aufzuziehen, um nachfolgend die wiederum translatorische Bewegung des Sprungschlittens in eine rotatorische Hauptbewegung der Abtriebswelle und in eine damit verbundene eigentliche Kontaktbetätigung zu überführen. Diese aufwändige Wandlung einer Drehbewegung in eine translatorische Bewegung und wieder zurück in eine Drehbewegung erfordert einen hohen Platzbedarf der Kraftspeicherkonstruktion innerhalb des Laststufenschalters und zudem eine Vielzahl komplexer einzelner Baugruppen.It is used an initial slow rotational movement of the drive shaft to translate a lift carriage to subsequently convert the turn translational movement of the jump carriage in a rotational main motion of the output shaft and in an associated actual contact actuation. This complex conversion of a rotary movement into a translatory movement and back into a rotary motion requires a large space requirement of the force storage structure within the on-load tap-changer and also a large number of complex individual assemblies.
Vor diesem Hintergrund schlägt die Erfindung die Gegenstände der unabhängigen Ansprüche vor. Die Unteransprüche betreffen dabei besonders vorteilhafte Weiterbildungen der Erfindung.Against this background, the invention proposes the subject matters of the independent claims. The subclaims relate to particularly advantageous developments of the invention.
Die allgemeine erfinderische Idee besteht darin, sowohl die Wählerkontakteinheit, als auch die Schaltmittel zur unterbrechungslosen Lastumschaltung mittels eines gemeinsamen Motorantriebes ohne Zwischenschaltung eines Energiespeichers zu betätigen.The general inventive idea is to operate both the selector contact unit, as well as the switching means for uninterrupted load switching by means of a common motor drive without the interposition of an energy storage.
Nach der Erfindung wird von dem Motorantrieb sowohl eine Gewindespindel angetrieben, die ihrerseits mit der Wählerkontakteinheit in Wirkverbindung steht, als auch eine Nockenwelle, mittels der die Vakuumschaltröhren betätigbar sind. Dies ermöglicht auf besonders vorteilhafte Weise eine einfache Betätigung der Wählerkontakteinheit unabhängig von den Vakuumschaltröhren.According to the invention, the motor drive both a threaded spindle is driven, which in turn is in operative connection with the selector contact unit, as well as a camshaft, by means of which the vacuum interrupters are actuated. This allows in a particularly advantageous manner, a simple operation of the selector contact unit independently of the vacuum interrupters.
Nach einer bevorzugten Ausführungsform der Erfindung weist der Laststufenschalter ein an der Unterseite des Transformatordeckels befestigtes Getriebemodul auf, das mit dem an der gegenüberliegenden Außenseite des Transformatordeckels angeordneten Motorantrieb zusammenwirkt. Das Getriebemodul weist hierfür ein flanschartiges Dichtmodul auf, das direkt an der Unterseite des Transformatordeckels angeordnet ist und mit dem Motorantrieb lösbar verbunden, insbesondere verschraubt, ist. An dem Getriebemodul ist zudem der gesamte Laststufenschalter befestigt. Damit hat das Getriebemodul sowohl die Aufgabe, den Laststufenschalter zu halten, als auch mittels des Dichtmoduls gegenüber der Außenseite des Transformators abzudichten. Verwindungen des Transformatordeckels beim Transport des Trafos werden somit nicht an den Laststufenschalter übertragen. Zudem kann damit ein Anschlussflansch mit überfräster Dichtfläche am Transformatordeckel entfallen. Darüber hinaus bietet diese Art der vorgeschlagenen Befestigung eine für den Transformatorbauer einfache Montage des Laststufenschalters innerhalb des Transformatorkessels.According to a preferred embodiment of the invention, the on-load tap-changer has a transmission module attached to the underside of the transformer cover, which cooperates with the motor drive arranged on the opposite outer side of the transformer cover. The gear module has for this purpose a flange-like sealing module, which is arranged directly on the underside of the transformer cover and releasably connected to the motor drive, in particular screwed, is. On the transmission module, the entire on-load tap-changer is also attached. Thus, the gear module has both the task of holding the on-load tap-changer, as well as seal by means of the sealing module with respect to the outside of the transformer. Twists of the transformer cover during transport of the transformer are thus not transmitted to the on-load tap-changer. In addition, a connection flange with overfilled sealing surface on the transformer cover can be dispensed with. In addition, this type of proposed attachment provides a simple for the transformer manufacturer mounting the on-load tap-changer within the transformer tank.

A selector contact unit in each case comprises a sliding carriage and a contact carrier for receiving the movable selector contacts, which interact with the fixed selector contacts.
Nach einer wiederum weiteren Ausführungsform der Erfindung werden die beweglichen Wählerkontakte jeweils an einem Kontaktträger aufgenommen und wirken mit festen Wählerkontakten zusammen, derart, dass die einzelnen festen Wählerkontakte durch eine Längsverschiebung der beweglichen Wählerkontakte samt Gleitschlitten, also der Wählerkontakteinheit, entlang der Führungsstange beschaltbar sind. Durch die Hin- und/oder Herbewegung der Wählerkontakteinheit werden die einzelnen festen Wählerkontakte beschaltet und damit der Regelbereich des Laststufenschalters durchlaufen.According to yet another embodiment of the invention, the movable selector contacts are each accommodated on a contact carrier and cooperate with fixed selector contacts, such that the individual fixed selector contacts by a longitudinal displacement of the movable selector contacts including sliding, ie the selector contact unit, along the guide rod can be connected. By the back and forth movement of the selector contact unit, the individual fixed selector contacts are connected and thus go through the control range of the on-load tap-changer.
